This study investigated how people's beliefs regarding their vocational abilities (i.e., career decision self‐efficacy) are associated with their perceived academic control, self‐liking, and self‐competence. It also assessed the relevance of these 4 types of self‐beliefs for personal job optimism among 268 Croatian college students. Results indicated that participants' career decision self‐efficacy and perceptions of their chances of finding jobs nationwide were significant predictors of personal job optimism. Furthermore, the influences of self‐competence and perceived academic control on personal job optimism were mediated by career decision self‐efficacy. These results extend previous research and may be informative for vocational guidance interventions. 相似文献

This study examined the relationship between proactive personality and career decision‐making self‐efficacy. In Study 1, the authors validated the Proactive Personality Scale–Korean Short Form, using the Rasch model with 315 participants, and found that fit statistics, point‐measure correlations, and item difficulty estimates satisfy the construct validity criterion. In Study 2, the authors administered the Proactive Personality Scale, Career Decision‐Making Self‐Efficacy Scale, and Career Search Self‐Efficacy Scale to 296 freshman and sophomore college students. Hierarchical regression analyses showed that proactive personality scores explain additional variance in both career decision‐making self‐efficacy and career search self‐efficacy scores. Implications for theory and practice are discussed. 相似文献

Hagopian, Rooker, and Zarcone (2015) evaluated a model for subtyping automatically reinforced self‐injurious behavior (SIB) based on its sensitivity to changes in functional analysis conditions and the presence of self‐restraint. The current study tested the generality of the model by applying it to all datasets of automatically reinforced SIB published from 1982 to 2015. We identified 49 datasets that included sufficient data to permit subtyping. Similar to the original study, Subtype‐1 SIB was generally amenable to treatment using reinforcement alone, whereas Subtype‐2 SIB was not. Conclusions could not be drawn about Subtype‐3 SIB due to the small number of datasets. Nevertheless, the findings support the generality of the model and suggest that sensitivity of SIB to disruption by alternative reinforcement is an important dimension of automatically reinforced SIB. Findings also suggest that automatically reinforced SIB should no longer be considered a single category and that additional research is needed to better understand and treat Subtype‐2 SIB. 相似文献

The purpose of this study was to investigate the effects of signaled transitions from relatively rich to lean conditions of food reinforcement on drinking concurrently available water or sucrose‐sweetened water in rats. Past research demonstrated that these negative incentive shifts produce behavioral disruption in the form of extended pausing on fixed‐ratio schedules. Four male Long‐Evans rats operated on a two‐component multiple fixed‐ratio fixed‐ratio schedule. In one manipulation, the ratio was held constant and the components arranged either a large six‐pellet reinforcer (rich) or small one‐pellet reinforcer (lean). In a second manipulation, the components both produced a one‐pellet reinforcer but differed in terms of the ratio requirement, with the rich and lean conditions corresponding to relatively small and large ratios. In both manipulations, components were pseudorandomly presented to arrange four transitions signaled by retractable levers: lean‐to‐lean, lean‐to‐rich, rich‐to‐rich, and rich‐to‐lean (the negative incentive shift). During experimental conditions, a bottle with lickometer was inserted in the chamber, providing concurrent access either to tap water or a 10% sucrose solution. The negative incentive shift produced considerably more drinking than the other transitions in all rats during both manipulations. The level of drinking was not polydipsic; rather, it appears that the negative incentive shift enhanced the value of concurrently available reinforcers relative to food reinforcement. 相似文献

Extended pausing during discriminable transitions from rich‐to‐lean conditions can be viewed as escape (i.e., rich‐to‐lean transitions function aversively). In the current experiments, pigeons’ key pecking was maintained by a multiple fixed‐ratio fixed‐ratio schedule of rich or lean reinforcers. Pigeons then were provided with another, explicit, mechanism of escape by changing the stimulus from the transition‐specific stimulus used in the multiple schedule to a mixed‐schedule stimulus (Experiment 1) or by producing a period of timeout in which the stimulus was turned off and the schedule was suspended (Experiment 2). Overall, escape was under joint control of past and upcoming reinforcer magnitudes, such that responses on the escape key were most likely during rich‐to‐lean transitions, and second‐most likely during lean‐to‐lean transitions. Even though pigeons pecked the escape key, they paused before doing so, and the latency to begin the fixed ratio (i.e., the pause) remained extended during rich‐to‐lean transitions. These findings suggest that although the stimulus associated with rich‐to‐lean transitions functioned aversively, pausing is more than simply escape responding from the stimulus. 相似文献

Prolonged space flight, specifically microgravity, presents a problem for space exploration. Animal models with altered connections of the vestibular ear, and thus altered gravity sensation, would allow the examination of the effects of microgravity and how various countermeasures can establish normal function. We describe an experimental apparatus to monitor the effects of ear manipulations to generate asymmetric gravity input on the tadpole escape response. To perform the movement pattern analysis, an imaging apparatus was developed that uses a high‐speed camera to obtain time‐resolved, high‐resolution images of tadpole movements. Movements were recorded in a temperature‐controlled test chamber following mechanical stimulation with a solenoid actuator, to elicit a C‐start response. Temperature within the test cell was controlled with a recirculating water bath. Xenopus laevis embryos were obtained using a standard fertilization technique. Tadpole response to a controlled perturbation was recorded in unprecedented detail and the approach was validated by describing the distinct differences in response between normal and one‐eared tadpoles. The experimental apparatus and methods form an important element of a rigorous investigation into the response of the tadpole vestibular system to mechanical and biochemical manipulations, and can ultimately contribute to improved understanding of the effects of altered gravity perception on humans. 相似文献

REBEL WITHOUT A CAUSE: A PSYCHOANALYTIC AND FAMILY‐LIFE‐CYCLE VIEW OF EMERGING ADULTHOOD IN THE FILM

The period during which grown children leave home and establish a new, self‐supporting family is called emerging adulthood. This paper uses psychoanalytic concepts and family‐life‐cycle theory to analyze the film Rebel without a Cause ( 1955 ) as a dramatic example of three families going through this phase. Freud's ( 1910 ) rescue‐motif of the child trying to save an endangered peer to repay his parents for having been nurtured is also characteristic of this period and is considered practice for parenting the next generation. Proximate conflict and support enable two of the film's families to continue the path to reproduce themselves. 相似文献

FROM EXTENSION TO REVOLUTIONARY CHANGE IN CLINICAL PSYCHOANALYSIS: THE RADICAL INFLUENCE OF BION AND WINNICOTT

This paper addresses the radical departure of late Bion's and Winnicott's clinical ideas and practices from traditional psychoanalytic work, introducing a revolutionary change in clinical psychoanalysis. The profound significance and implications of their thinking are explored, and in particular Bion's conception of transformation in O and Winnicott's clinical‐technical revision of analytic work, with its emphasis on regression in the treatment of more disturbed patients. The author specifically connects the unknown and unknowable emotional reality‐O with unthinkable breakdown (Winnicott) and catastrophe (Bion). The author suggests that the revolutionary approach introduced by the clinical thinking of late Bion and Winnicott be termed quantum psychoanalysis. She thinks that this approach can coexist with classical psychoanalysis in the same way that classical physics coexists with quantum physics. 相似文献

Initial exertion of self‐control has been suggested to impair subsequent self‐regulatory performance. The specific cognitive processes that underlie this ego depletion effect have rarely been examined. Drawing on the dual‐process theory of executive control (Engle & Kane, 2004 ; Kane & Engle, 2003 ), the current meta‐analysis revealed that initial self‐control exertion impairs participants’ capacities of maintaining the task goal but its effect on capacities of resolving response competition is in need of further investigation. Our results are more consistent with recent theoretical views that consider ego depletion as a switch cost and a result arising from reduced motivation to engage in further self‐control. 相似文献
